Abstract

A process and device are disclosed for regulating the torque (MIND) derived from a drive unit, whereby in a gear shifting unit a target torque value (MIG) is determined in accordance with a target torque value (MIFA) set by the driver. In addition, a limiting torque value is pre-set to protect the transmission and limit the torque derived from the drive unit.

Es ist Aufgabe der Erfindung, Maßnahmen anzugeben, mit deren Hilfe das Drehmoment einer Antriebseinheit über einen Sollmomentenwert auch im Zusammenhang mit einem automatischen Getriebe eingestellt werden kann, ohne daß von der Getriebesteuerung derartige Sollwerte vorliegen. It is an object of the invention to provide measures by means of which the torque of a drive unit for a desired torque value also associated with an automatic transmission can be adjusted without the presence of the transmission control such setpoints.

Dies wird durch die kennzeichnenden Merkmale der unabhängigen Patentansprüche erreicht. This is achieved by the characterizing features of the independent claims.

Besonders vorteilhaft ist, daß diese Vorgehensweise bei Steuersystemen eingesetzt wird, bei denen keine Momenteninformation zwischen Getriebesteuereinheit und Motorsteuereinheit übertragen wird, bzw. im Fehlerfall dieser Übertragung bei Steuersystemen, bei welchem Momentensollwerte von Getriebesteuerung zur Motorsteuerung übermittelt werden. It is particularly advantageous that this procedure is used in control systems in which no torque information between transmission control unit and engine control unit is transmitted, or in case of failure of this transfer in control systems, are in which torque setpoints of transmission control transmitted to the motor controller.

The procedure described is, is carried out under the program of a microcomputer of the control unit 10thDie Struktur dieses Programms ist anhand des Übersichtsblockschaltbildes nach Fig. 2 dargestellt. The structure of this program is illustrated by the overview block diagram in FIG. 2.
